FAQs

Can I remove the key while it’s unlocked?

No—the key only comes out when it’s locked. This helps prevent accidental unlocking.

Is it heavy to carry?

It weighs 2.5 pounds—solid enough for security but still portable for backpacks or saddlebags.

Is the chain weatherproof?

Yes, the cloth sleeve helps prevent rust and keeps the chain looking clean over time.

Can it be used on things other than bikes?

Definitely. It’s a solid choice for securing gates, fences, grills, or tools too.

Is it safe to use in high-crime areas?

It offers strong deterrence, but no lock is 100% theft-proof. Avoid leaving it unattended overnight in high-risk areas.
